All Go Pluses will be the same no matter where you get them from, or are you suggesting the Gotcha which is made by some one else and is not endorsed by Niantic?
Ok @mythrield90 found my daily logs.
I originally bought the Go Plus mainly for spinning stops to and from work to keep the bag topped up. I thought it was crap for catching at first as my first lap around the block at home had 7 Dust Off in a Row. When I thought about it more I thought if have it set for both Pokemon and Stops to and from work what does it matter what Pokemon get away as I wasn’t catching them manually anyway due to stopping, spinning the stop and driving off straight away anyway.
This was done earlier in the year when it was easy to work out XP and Dust Values as every thing was only worth 100 Star Dust. You couldn’t do it easy now as you would have to account for every stage evolution Dust value caught and now the whether match bonus. XP is still easy as it only throws normal throws with basic catch.
I did this over 18 days (4 weeks) using the Go Plus to and from work as well as using it at work where Red Balls permitted (work use was only done to help get the sample size over 1K). The biggest issue was not having enough Red Balls to use it more and regular recording the logs from the journal. A few times I missed some data as my encounters had exceeded the journal capacity to see results.
1308 Pokemon Encounters
749 Caught @ 57%
569 Dusted @ 43%
112350 XP from Catches
14225 XP from Dusted
126575 Total XP Gained
74900 Star Dust
You would never buy a Go Plus/Gotcha to replace having to swipe the screen throwing balls as that’s just crazy. It is a great add on accessory that when used in situations where playing normally is not possible can help collect Star Dust and XP to accelerate leveling up as my results above show. The Star Dust alone is enough reason to be using one.
No way would I be on L40 now without the Go Plus.
